Wen the juubi gets weak sasuke will seal it ...sasuke is weak against narutos full form this amaterassu wont do much good if naruto uses tbb so sasuke needs d juubi... good thread
Thank you

I also agree.
It also makes sense in regards to the 'mirroring competetiveness' between Naruto and Sasuke as we know Naruto also has the Chakra of the tailed beasts within him already; meaning that if kishi chooses to take this competetiveness right down to the grain Sasuke would also stand a good chance of weilding the Juubis (tailed beasts) Chakra.
I believe also that there is more to come from Naruto to this end and his connection to Rikudou Sennin, however, the possibility of a final epic battle between the two i feel is still on the cards.
It is my belief that Sasuke, and especially OROCHIMARU (although for different reasons) are biding their time. Sasuke is Known to be unpredictable. Orochimaru is predictable in the sense that we all know he is a snake. This in effect could explain why Orochimaru is now suddenly 'following' Sasuke reason being that if this is true, Sasuke would play directly into Orochimarus hand by his own apparent 'will' (the final outcome being what Orochimaru wanted)
This could be part of the reason Oro stated that he respected Sasuke over Kabuto, as Kabuto was merely trying to 'immitate' Orochimaru whereas Sasuke has a strong will of his own, which in the end could subsequently benefit Orochimarus aims.
